improve' the construction ci incastri-ing;J

instruments, and to provide zi. con'ibined level and plumb .ridftpted to be employerl es an inclinoineter -lor determining Whether objects are level, plumb or inclined, mid for ascertaining the ongle or degree ot inclinan tion, if inclined.-

AWith these and other objects in view, the invention consists in the construction and novel 'combination of perts hereinafter iullj. described, illustrated in the accompanying drawing, and pointed out in the claims hereto appended; it being understood that vurious changes in theiorm, proportion, size and minor details ot' construction, within the scope of the claims, may be resorted to withl Out depertinglrom the spirit or sacrificing' any of the cdvantnges ol the iswcni'ion.

In the drawingz---liignre l :i pi'xrspective View of a combined level und plumb, constructed in accordance with this ii ention, and shown folded. F151'. is s.. side erm' non partly in section., the stoel-z or body or the level being in en inclined position, and the plumb being` vertical. Fig. 3 is e transn verse 'sectional view,illustrating the manner of moving .the plumb. Fig. lis e dot-eil view, illustrating the construction olr the ratchet head of one of the sections of they pivot.

Like numerals oi: reference designate conv responding ports in ell the figures o'i" the l designstese-levelsto-` Y Y coimposed of `two sections :ind desi?, A. ,d to be constru-steil of Wood, or other snimblc nmterinl. The sections are detaehabljf secured tog-oi her by screws 1", or other suitable fastening de vices, which have their heads arranged in recesses or sockets of the contiguous section of the level stock or body.

The level stock or body is provided et en intermediate point with a. recess 2, and the Wall 3 at one side of the recess is convexly curved to This Well of l l a i l i i l i l l 'Y filo,

-the curved Wall 3 ol" the recess, as cle the recess 2 is provided with c slot 4 to receive the needle portie of e. pointer or indicator- 5, which is mounted within the stock or body on a transverse pivot and which is provided with a. suitable weight 7 for maintaining the poinibr or indicator in a perpendicular position. The level stock or body is provided with an' interior chamber 8 for the indicator or pointer, and :i curved plete 9 is secured to shown in li" `l und ol' the drawing. 'l d .ruis-wed plaid, f is provided with c slot il), to correspond with the slot 4 of the stock or body, and it has graductions 1l at oppo-l sito sides'cf the slot l0. The pointer or indicetor is edufpted to swing between the graduations, and its position may be accurately ascertained et either side of the level or body. The degree of elevation of the level stock or body, when the latter is arranged et en inclination, is indicated by the pointer.

Guards 152 are preferably employed Jfor preventing any object from falling into the rer-rss L and injnri the indicating means. ',lhel guards ilconsist of parallel rods or pieces spanning the recess, and externlingI longitudinally ol the stock or body, and suitably .sr-mired at their terminals to the verso pivot located adjacent to one end of the seid stock or body, sind composed of adjustable ronncoting sections i5 ond lo. The sont in l5 is provided with :irnli'hel head l?, having' peripheral .ratchet teeth 'for engaging am annular series of ratchet notches l'c of' the level stock or body. yThe a Million, is provided zit its inner portion with unile threads fovrr'mmiging icnnile threads il the 'in secti. ich is tubular and n'hirri is provided at its outer end with n head 20. The section 16 of the pivot is supported adjnccnt to its outer end by n bravo '21, secured to the level stock or body und having :in :inguliirly bent np'proximntcly L-shnped' portion 22, which is providml with :i perforation For the reception of the pivot 14. The washer 23, which mounted on the pivot 14 is interposed be tween the plumb and the level stock or body, and the tubular section 16, which is ad'justable, is provided at its outer end with a.4 pivotcd winged grip, or handle portion 24,

which is adapted to be folded against the brace. The plumb 13, which consists of a bar, is provided at its slot 25, and it has a weight 26l at the other end. The bar of the plumb may be conveniently constructed of Wood, and the weight 26 preferably consists of a block orpiece of lead, suitably secured to the lower end of the plumb. When the measuring instrument is not in use, the plumb may be folded alongside the stock or body, andthe weighted end of the lumbn is received within a keeper 27, consisting of a substantially rectangular Y loo projecting from one side of the stock` or bo y, and the slot 25 enables the Weighted end of the plumb to be readily introduced into and removed from the keeper.

In the use of the device, the plumb will- .v In various operations of car entry where itis desirable to plumb an uprig t, and ascertain an angle with relation to such upright, the instrument will be found more advantageous than a separate plumb and a separatel inclinometer, 'owing to the combination of 'these' two instrumentsv in one, and' also because'theplumb bar and the level stock or body, may be clamped together to preserve their relative adjustment. l

Havin thus fully described my invention, what I c aim as new and ,desirel tosecure by Letters Patent, isz- 1. .An instrument oi the class described comprising alstoclr or body having a level, a

plumb bar pivotally connected with the stock or body at,one side thereof, a substantially LI-shaped keeper extending laterally 1from the stock or body and arranged to receive the free endof the. plumb bar, land means located at the' said pivot for permitting the plumb bar to have a limited longiivoted end with ay The device is adapted to be' tudinal movement to introduce it into and 'remove it from the keeper. and for clamping the said plumb 'bar inengagement with. the keeper.

2. An instrument' of the class described `comprising a stock' orf'body havin a' level, a plumb consisting of a bar .provi ed with a slot, a pivot passing through the slot and securing the plumb to the stock or body, ay keeper consisting of a loop and arranged to receive the plumb, and means mounted on the pivot for clamping the plumb bar in engagement with the keeper.

3. An instrument ofthe class described i comprising astock or bod having a plu-- rality of ratchet notches, a p umb bar, and an adjustable pivot' for the plumb lbar forming a ciamp for the tsame and 4having a ratchet head engaging the notches of thestock or body, the latter carrying a level`- Y 4.' An -nstrument. of thel class` described comprising a stock or body having a plurality of ratchet notches, a'plumb bar,'and a pivot connecting the plumb bar' to the stock or bodyand composed of two adjustable' connecting sections, one of the sections being provided Witlia ratchet head for engaging the ratchet of the lstock or body, said body carrying a level at an intermediate point of its length.

. 5. An instrument of the class described comprising a vstock or body havinga level, a i

plumb b ar pivotally connected with the stock or body at one end thereof, a. keeper extending laterally from the stock or 'body and arranged to receive the free end ot the plumb bar, and means located vat/the said pivot for permitting the plumb to-l:uive,'al

limited longitudinal movement to introduce it into and remove it from the keeperfandior clamping the plumb barin engagement'with the. keeper.

In testimony, that I claim the foregoing as l my own, I have hereto aiiixed my signature 1n the presence of two witnesses.
